Avionics
- New databus 1553B standard to incorporate newer avionics
- New mission computers, navigation system (RLG-INS w/GPS + possible Glonass module - Sagem's Sigma95N), Stores Management System, new VRS (Video Recording System) plus DMG (Display Map Generator). VRS and DMG likely to be sourced from Israel or locally.
-Glass cockpit with new HUD, two MFDs, HOTAS
-Zhuk ME MultiFunction radar with A2A/A2G modes; new IFF; Zhuk variant for IAF is Zhuk M2E, with an improved signal processor over Indian Navy MiG-29Ks which received the Zhuk M1E (source:AWST
Sharper Eyes for India's MiGs) The improved processor would allow for improved raid assessment, and NCTR (non cooperative target recognition).
Deputy Director (Phazatron) Yuri Goskov quoted:
Guskov said that Phazotron is already working on the next modification of its slot array radars, the Zhuk M2E. This version will have a faster processor, allowing it to classify targets by type (for instance, fighters, bombers and helicopters) and to break-out formation targets flying at 20-30 meters apart. The radar can also be programmed to identify aircraft by type – in the case of a new type, it can record its reflected signal and later use it for identification.
The Zhuk M2E should start flight testing this year. The modernized radar will equip 62 Indian Air Force MiG-29s that MiG is modifying to the MiG-29UPG configuration under contract to the IAF.
-NIPP OLS-UE (as on latest MiG-35 and MiG-29K). Has a TV channel. Also has an advanced IR matrix for increased range. For the MiG-35, MiG notes
"The IRST system with infra-red, TV and laser sighting equipment has been developed using the space technologies which were not applied previously in aviation. The system distinctive features are the increased range, detection, tracking, identification and lock-on of air, ground/surface targets in the forward and rear hemispheres, at day and night measuring the distance with laser range-finder as well as the formation of target designation and laser illumination of ground targets. The IRST system and new helmet-mounted target designation system are integrated into the armament control system." The IAF SMT upgrade does not have the fuselage mounted pod, so it cannot track ground targets (IAF will use the Litening instead) but rest applies, for the forward facing IRST.

D-29 EW suite: Developed by DRDO with inhouse high accuracy DF RWR fit which cues AESA jammers. Latter codeveloped with Elettronica. DARE developed a high performance EW system with a scalable, modular architecture. The system can receive signals from multiple channels, process them in an Indian developed signal processing suite, and then devise appropriate jamming countermeasures to be initiated by jammers linked to the output channels. The LCA & MiG-27 Upgrade, both feature conventional Transmitter based jammers but the MiG-29 has an AESA fit developed with Elettronica. This system combines high grade coverage with high ERP (Emitted Radiated Power) for effective countermeasures.
-Improved chaff & flares system: Likely to be the locally developed system by Bharat Dynamics Ltd.
-V/UHF radio fit + IAF datalink. Radios likely to be Software Defined Radios developed by HAL
-VOR/ILS/TACAN from HAL
Weaponry
-R73E,R77, KH-35UE, KAB-500/1500, Kh-31 A/P family missiles, Kh-29 L/T (see table below for complete list from Russian side)
Other systems to be added will be the local Astra BVR AAM (Mk1 and Mk2), and the Sudarshan family LGBs
Fuel
The IAF upgrade carries the typical SMT class humpback. Range is now increased by around 50% over original MiG-29, increasing endurance at typical operating radius. IAF MiG-29s can also carry both wing plus fuselage fuel tanks, 1500 L each. The new fit also includes IFR.
New Engines
Under a separate deal, HAL will supply new RD-33s manufactured under license from Klimov. These are RD33 Series 3 engines.
